Have had my 1st GRiSO ('17) 1 month. I've noticed numerous mentions of Beetle's maps. I have 3 questions.
1) Cost of a map?
2) I don't have computer & wouldn't know how if I did. Who can do it at what additional cost?
3) How necesary is a map change if I plan on keeping the oem silencer? I'm not looking for increaseed performance, at 68 it feels great as is.
Thanks in advance.
